Radeon RX 6600 XT vs GeForce GTX 1660 SUPER: In-Depth Breakdown
Performance: Radeon RX 6600 XT vs GeForce GTX 1660 SUPER
The Radeon RX 6600 XT is dramatically faster, around 64% ahead of the GeForce GTX 1660 SUPER. That gap is enough to move it up a tier: the Radeon RX 6600 XT is comfortable at 1080p, while the GeForce GTX 1660 SUPER is better matched to entry-level 1080p.
Power & Efficiency
The GeForce GTX 1660 SUPER pulls less power (125W vs 160W), so it's the easier card to cool and the lighter load on your PSU. The faster Radeon RX 6600 XT draws more overall but extracts more performance from each watt — plan for a sturdier power supply if you pick it. Its more modern RDNA 2 architecture on a TSMC N7 process is part of why it does more with each watt.
VRAM & Future-Proofing
With 8GB against 6GB, the Radeon RX 6600 XT has more headroom for 4K textures and memory-hungry creative/AI tasks where the GeForce GTX 1660 SUPER's 6GB can fall short.
Generation & Longevity
The Radeon RX 6600 XT is roughly 2 years newer than the GeForce GTX 1660 SUPER (RDNA 2 vs Turing), so it generally benefits from a more modern architecture and longer driver-support runway.
Features & Ecosystem
Beyond raw numbers, the GeForce GTX 1660 SUPER brings NVIDIA DLSS upscaling/frame generation and stronger ray tracing, while the Radeon RX 6600 XT offers AMD FSR upscaling and strong rasterization value. If you lean on upscaling or ray tracing, that ecosystem difference can matter as much as the frame-rate gap.
Which should you buy: GeForce GTX 1660 SUPER or Radeon RX 6600 XT?
The Radeon RX 6600 XT is the faster card by about 64%. With live pricing limited for this pair, base your decision on the spec differences above — particularly VRAM and power draw — and check current stock before buying.
